A lot of the DX2 computers (50mhz, 66mhz)(the speed doubler ones) comes
with heatsink attached the the chip. There was reliability problems with
these chips for the longest of time before they were eventually release.
Heat sink to cool it down (somewhat) was one of the ways of helping the
situation along with other modifications I think. Check out the other
newsgroups like comp.sys.intel, comp.arch, or comp.sys.ibm.pc.hardware
for more info. I can't remember the whole story. Try touching a DX2
chip after the computer has been on for awhile (1 hr?). It gets a lot
hotter than the normal chips which only gets warm.
